It is testified that the wood-plastic composites belong to brittle material by tension test and compression test and that the tension elastic modulus is practically equal to the compression elastic modulus.
The results showed that PP-g-MAH can improve the compatibility of PP wood-plastics composites,and especially,when the use amount of compatibility is 10phr,and its graft ratio of PP-g-MAH is 1%~1.5%,the comprehensive properties of wood-plastics composites are greatly improved.
The influence of particle size,microstructure and content of wood flour on the mechanical properties of wood flour and plastic composites were studied.
To have a better knowledge of the phenomena that affect the adhesion characteristics of wood plastic composites (WPCs) a series of surface treatments was performed.
Most of the surface treatments improved the adhesive bondability of wood plastic composites and, particularly, the smoothest WPC surfaces increased the shear strength by 100% with respect to the control.
The impact of two coupling agents, maleic anhydride (coupling agent 1) and isocyanate (coupling agent 2) on the properties of wood-plastic composites (WPC) was studied.
Wood-plastic material from a novel reactive processing method (co-refining by steam-explosion) was investigated by 13C solid state nuclear magnetic resonance (NMR) and dynamic mechanical analysis (DMA).
Information about the acid-base characteristics of these materials should be useful to improve the intermolecular bonding properties in wood-plastic composites.
